TWO Spitfire fighter planes flew over RAF Bentley Priory on Thursday evening as part of a closing ceremony for the base.

The base, which is currently home to the Defence Aviation Safety Centre, Air Historical Branch and Ceremonial and Protical Branch, is due to relocate all its units to RAF Northolt in February next year.

The closing ceremony included a flying display by the Battle of Britain Memorial Flight.

The RAF base was the Fighter Command's headquarters when Britain fought a four-month battle with the Luftwaffe in 1940 when around 550 officers died in the battle.

Prime Minister Winston Churchill monitored the landings from the Allied Expeditionary Air Force War Room underneath Bentley Priory.

Chief of the Air Staff, Sir Glenn Torpy, will addressed guests at the ceremony including Defence Minister Lord Drayson and 15 of the Battle of Britain veterans.

The historic air base and its gardens will be opened to the public after the relocation.
